Chennai/New Delhi: In the biggest seizure of cash and gold post demonetisation, the Income Tax department yesterday said it has seized unaccounted assets worth over Rs 142 crore — that includes about Rs 10 crore in new notes and gold bars weighing 127 kg — during searches at multiple locations in Chennai to check tax evasion.

This largest seizure of new currency notes in the country, after the old Rs 500/1,000 notes were scrapped on November 8, was by the sleuths of the investigation wing of the Income Tax department after raids were launched yesterday on eight premises of a group engaged in sand mining in Tamil Nadu.
